Javascript while loop failure

Question

Into a php page I have 20 text boxes. I want to make a button, using javascript, and when user clicks on it the rest 19 text boxes to take 1st text box's text. I have done something like this but it isn't working... Any idea?

function Throw_PhotoStuff(){
 var pcount=1; 
 while(pcount<20;){
 document.getElementById('photo_'+pcount).value = document.getElementById('photo_1').value; pcount++;
 }
}

• MaVRoSCy: your code looks good. Where is the html? And what isn't working? Any error in console?

• Simos Sigma: As Sudhir wrote below, it was a syntax error. I should remove the semicolon from while(pcount<20;) to while(pcount<20). Thank you all guys!

Answer 1

remove the semicolon from while loop, like:

while(pcount<20;){ //will show SyntaxError: missing ) after condition

to

while(pcount<20){

Answer 2

I think you have extra semicolon here while(pcount<20;){

remove this
